4. C. MacOwaniana, Schonl. et Bak. fil., var. crassifolia, Schonl., 

 n. var. 



" Little Namaqualand. Bush, 2-3 ft. Granite hill behind Nieuwe 

 Bust, 5503." 



In the structure of the flowers there is practically no difference 

 between this and the type. The leaves are, however, much thicker 

 and shorter, being only circ. 2 cm. long, whereas in the type they 

 reach a length of 6 cm. They are here circ. 5 mm. thick, whereas 

 in the type they hardly reach this thickness. They are almost 

 fusiform. 



5. C. rudis, Schonl. et Bak. fil., in Journ. of Bot., Aug., 

 1902. 



" Little Namaqualand. Among bushes near roadside between 

 Stinkfontein and Garies, 5645." 



This number comes from the same neighbourhood as the type „of 

 Cr. rudis. As far as can 1)9 judged from the rather meagre material, 

 it agrees with it in floral structure, in the filiform peduncle, and the 

 few-flowered lax inflorescence. The shape of the leaves is also 

 similar, but their length is circ. 2 cm. as compared with circ. 1 cm 1 , 

 in the type ; further, the stem is much longer here, namely, circ. 

 30 cm. 



6. C. connivens, Schonl., in Bee. of the Albany Museum, ii., 

 p. 141. 



" Bush, 1-liy ft. high. Leaves white. Amongst rocks in Middle 

 Khamiesberg, circ. 4,000 ft., 6342; 15.1.11." 



The sepals are a trifle longer than in the type and are propor- 

 tionately narrower ; the petals are a trifle shorter than in the type. 

 The white colour of the leaves is due to the fact that the cuticle 

 becomes detached and air gathers underneath it. 



7. C. albiflora, Bot. Mag., t. 2391, var. minor, Schonl., n. var. 



" Cape Region. Flowers white. Bush up to 2 ft. Stems erect. 

 Upper north-east slopes above Pickenier's Pass, 5130 ; 24.11.10." 

 " Little Namaqualand. Lower middle slopes of Sneeuwkop, 5840." 

 These are close to a plant labelled Cr. albiflora minor in Har- 

 vey's Herbarium. They differ from the type in having more laxly 

 leafy stems, somewhat smaller and narrower leaves, more laxly 

 branched inflorescence, and slightly smaller flowers. Further, the 

 bristles on the upper internodes of the stem are not so large as in 

 the type. Schlechter 9849, collected at Genadendal, agrees on the
